WHEEL MO'O'NTING FOR MOTOR-PROPELLED RAILWAY CARS.

Application filed December 5, 1921. Serial No. 519,836.

To all whom it may concern:

Be it known that I, ALFRED F. MASURY, a citizen of the United States,residing in the borough of Manhattan of the city of New York, in theState of New York, have invented certain new and useful Improvements inWheel Mountings for Motor-Propelled Railway Cars, of which the followingis a specification, reference being had to the accompanying drawing,forming a part hereof.

Much atteintion is being given to the development of rail cars propelledbyinternal combustion engines. The logical development of cars calls forthe adaptation to railway practice of conventional types of motorvehicles. The principal problem encountered at ever turn is to adapt thestandard equipment 0 motor cars to railway require ments. Such a problemis encountered, for instance, in the mounting for the tractor wheels onthe rear axle inasmuch as the standard gage of rails is less than thestandardgage of the treads of motor vehicles. It might seem at firstthat a motor car could be. operated satisfactorily on rails by merelyreplacing the traction wheels with car wheels.-

Such an interchange is not only impossible byreason of the difference ingages but would, if possible, be contrary to accepted railway practicein that the supporting axle housing does not revolve with the wheels butthe wheels, rather, rotate on bearings which are carried with the axlehousing. It is the object of the present invention to construct a wheelmounting for railway cars which may be adapted to the conventional partsof a motor vehicle with comparatively little expense and afford amounting whlch is at once simple, accessible and eflicient. A fur-- therobject of the invention is to provide a mounting for the traction wheelsof rail.

cars in which the supporting axle housing shall not revolve with thewheelsbut will support hearings on which the wheels revolve about thehousing. In accordance with this object of the invention therequirements of rail use have been adapted to acceptedautomotivepractise without sacrificing any of the desirable characteristics ofeither.

The invention will be described with great- 'er particularityhereinafter in connection with the illustrated embodiment thereof in thesingle drawing which shows, in vertical section, an improved wheelmounting for railway cars and a fragment of an actual housing and driveshaft of the character used in standard automotive practise.

It is usual in the automblle art in one type of final drive to provide adead axle tube through which extends a floating jack shaft to drive thetraction wheels. On the housing is usually mounted a spring seat. Sincethe gage of rails is narrower than the standard gage .for the treads ofwheels of automotive vehicles, it becomes a problem, if car wheels areto be mounted on the conventlonal parts of such a vehicle, to bring thewheels inwardly on the axle housing until they are spaced apart by adistance equal to the standard gage of rails. This has beenaccomplished, however, in-the present invention, in a very simple andinexpensive manner. The dead axle tube a has been shortened considerablyin its width and the live axle section b which is mounted rotatablytherein has been shortened to a corresponding extent. These parts are,nevertheless, retained in the relationship in which they are found, inconventional automotive ractise. The tube a has been machined o asindicated at a, for a considerable distance in order that the springseat 0 might be placed thereon inside of the wheel bearings 11, d, andin proper relation thereto. The spring seat a may be formed with ashoulder a to bear against a corresponding shoulder a on the tube a todetermine the innermost position of the spring seat and resist lateralmovement thereof. In like manner, the race member d ofthe wheel bearingd may rest against the outer edge of the spring seat 0 and thereby haveits innermost position determined and lateral movement resisted. Theinner bearing (1 of the wheel will be found at one side of the loadplane and the outer bearing (5' will be found at the other side of theload plane so as to 'give a proper appor tionment of stresses on thewheel e. The improved wheel itself includes an annular hub section 7which is shouldered interiorly at one end, as at f, to form an abutmentfor the outer race member d of the bearin (Z. T o the inner edge of thecentral hub mem er 7 may be secured acover plate f? through whichextends snugly the spring seat a, the association between the partsbeing such as to exclude dust and dirt from the hub and prevent reaseand oil from escaping therefrom. T e bearing d is disposed at theoppositeelld Of the hub member f. The hub member f has cast therewith anannular hub flange to which may be bolted the web of the wheel on thetelly of which is secured a suitable flanged tread 6'. At the outer sideof the web of the wheel 6 is secured an extension sleeve g to which isbolted, as by bolts h, a hub cap 2', which is splined on the end of thejack shaft 6. Bythis construction the The spring seat co-operates withthe wheel bearings and with. the tube so as to form a.

simple but secure disposition of parts. The

wheel itself is mounted to turn on the dead axle tube instead of, as inrailway practise,

' turning with thesupporting axle. The parts are inexpensive and simpleand very accessiv ble for assembling, replacement or repair. What Iclaim is: 1. Ina self-propelled motor railway car, a dead axle tube ofconventional automobile meme? design, a live axle section mountedrotatably.

therein, said tube and section being shortened to adapt them to-carrails of standard gage, means carried on the tube for seat- 1n si e ofsaid seat on the dead axle tube,one of said bearings having its innerrace in abutment with the edge of said seat, a flanged car wheel mountedon said wheel bearings, and means to connect the car wheel oper- 1atively with the live axle section.

2.-In a self-propelled motor railway car, a dead axle tube ofconventional automobile design, a live axle section mounted rotatablytherein, said tube and section being shortened to adapt them to carrails of standard gage, means carried on the. tube for seating a spring,whe'el bearings mounted outside of said seat on the dead axle tube, oneof said bearings having its inner race in abutment with the edge ofsaidseat, a flanged car wheel mounted on said wheeli bearings, means toconnect the car wheel oper atively with the the live axle section, and acover plate bolted to the wheel and revolving with the wheel about thespring seat in close engagement therewith.
